A man hides round a corner as fighting bulls from the ranch of Victoriano Del Rio Cortes run along the Curva de Estafetaa during the fourth day of the San Fermin Running Of The Bulls festival, on July 9, 2014 in Pamplona, Spain. The annual Fiesta de San Fermin, made famous by the 1926 novel of US writer Ernest Hemmingway 'The Sun Also Rises', involves the running of the bulls through the historic heart of Pamplona.

Chicago Native Who Authored Book On Surviving ‘Running Of The Bulls’ Was Mauled By A Bull

The author of a book on surviving Pamplona’s famed Running of the Bulls was mauled by a bull in the most recent event, according to the Daily News.

Chicago native Bill Hillmann authored the book “Fiesta: How to Survive the Bulls of Pamplona,” which was published in June. His friend and editor Alexander Fiske-Harrison called him the “best young American runner on the streets today” on his blog Tuesday, just one day before Hillmann was attacked.

A bull speared the 32-year-old in the leg. He was immediately taken into surgery and Fiske-Harrison said he is doing well, save for having some troubles breathing because of choking on irony.
